To all whom, it may concern Be it known that I, y lNarren, in the countyfof' Trumbiili and tate of Ohio, have invented certain new and useful Improvements in Paper-Feeding Devices; and I do hereby declare the following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

lThe primary object of this invention is to provide in a timed paper` handling -device, means for preventingstock being iinproperly fed, that is to say,'at the wrong time, thereby avoiding the waste 'which occurs fromuneven folding and printing out of register. It is well-known that if stock isLfed at the wrong time itwill be out of register either for printing or folding.`

VIn the accompanying drawing, Figure l is a side elevation, with parts omitted show-y ing, the feed stops and drop-roll raised. Fig. 2 is a similar view showing the parts iii the position they occupy when feeding, that is to say, with the -drop-roll and stops loweredand the guards raised. Fig. 3 is a plan View with the drop-roll omitted.

' Referring to the drawing, 1 designates a feed-roll which is located in the feed path se at the end of feed table 2 onto which the stock may be fed by any suitable means, the eriphery'of such feed-roll intersecting the plane of the feed table.

3 designates a series of stops in rear of e5 the feed-roll and designed, when raised, to project above or through the feed path and likewise above the periphery of lthe feed roll. By the term rea-r reference is meant.

to the delivery side of the feed-roll asv distinguished from the These stops are raised whenA a vdrop-roll 4 is elevated out of working engagement with the feed-roll, asshown in Fig. l, and likewise when such drop-roll is lowered stops 3 `are moved out of the feed path to allow lstock to be fed by the conjoint action of the two rolls.' I have shown the .stops 3 when raised, as in Fig. 1, asbeing in close relation to the opposed portions of the rolls 1 and 4 by which the stock is engaged.

Simultaneous With the lowering of the ydrop-roll and the withdrawal of the stops a series of guards 5 is causedto intersec. the plane of thefeed pat-h in front of the reedshould be fed while the CARL A. .lacci-ir,

the

, co-acting rolls are in operation it will be' arrested by tliegiiards and prevented from being taken up by the feed-roll.l Bythe terni in front reference is meant to the receiif'ing side of the feed-roll as distinguished from the delivery side thereof. As soon as the drop-roll is raised andthe stops are brought 'into their effective positions the guards will be lowered out of the way and allow the stock arrested thereby to pass to the stops in position to be taken up by the feed roll. rlie stops are sufficiently beyond the center of the 'feed-roll to allow the st ock'to be gripped between thetwo rolls. Likewise the guards are suiiiciently in front of the rolls to prevent the latter from takingl hold of the stock while arrested by such guards.

I do not restrict myself to any particular means of construction or arrangement for bringing about the necessary movements of the s tops, the drop-roll and the guards. According to the means shown the stops are formed on the free ends of arins 6 which are fast on a shaft 7 which may be partly reciprocated by any suitable means, such arms being bent or curved to partly encircle the feed-roll shaft so that they may be positioned between peripheral enlargements of the feed-roll. This shaft may also cause the raising and lowering of the drop-roll, the supporting frame of the latter being connected by a link S to an arm 9 of said shaft. The guards 5 are shown as consisting of fingers carried by a spring-held shaft 10 which is partly rotated, as againstthe tension of its spring, by a tappet 1'2 of shaft Taengaging a tappet 13 of shaft l0. YWhen the former shaft is turned to raise the stops and the drop-roll, shaft 10 is turned by its spring to withdraw the'guards.

The advantages of my invention will be readily appreciated by those skilled in the art. By means thereof waste of paper, resulting from irregular feeding, is avoided.-

I claim as my invention: p

A; feeding device comprising intermittently cooperating feed-rolls, movable stops for arresting stock between opposite 'portions of said feed-rolls when the latter are inactive, and guards for arresting stock i'n front of said feed-rolls when the latterl are roll, al drop-roll for c'operating therewith@ iin- - path-l in ystops designed to be moved into the feed path of'stock when said drop-roll is raised .to arrest stock 'between oppositejportions of said feed-rolls', moved into .such feed path infront-of the .feedfroll When said stops are Withdrawn 1nd sid drop-roll "is in Working relation to d into the feed path Whensaid stops tire-With-v drawn. therefrom andsaid drop-roil"1is"in' Working engagement with "sa-id feed-roll,
